[0002] A thermal transfer printer is a machine that uses piezoelectric printing and thermal foaming principles to perform printing operations. It does not cause changes in the properties of the ink and can be preserved for a long time. The printed objects can be preserved for a long time, are not easy to change color, and will not change with changes in ambient temperature.
[0003] In the existing field of portable thermal transfer printers, indicator lights are usually used to display different printer states to achieve human-computer interaction. Such indicator lights are relatively simple and crude, with uneven brightness and no aesthetic appeal, which cannot satisfy people's spiritual pursuit of beauty. If complex processes are pursued, the cost will also increase accordingly. In addition, the light guide mechanism is large and not suitable for being installed in a portable machine, resulting in uneven light guide brightness.
[0004] Now, a new type of bar indicator light structure is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the present invention is to provide a strip-shaped indicator light structure to solve the problem of uneven light guidance mentioned in the above background technology.

[0007] As a further technical solution of the present invention, the V-shaped light incident surface is symmetrically arranged on both sides of the main reflection surface, and the V-shaped light incident surface and the main reflection surface are in the same horizontal plane.
[0008] As a further technical solution of the present invention, the main reflection surface is arranged at the front end of the strip-shaped light guide, and the V-shaped light incident surface is sandwiched between the side reflection surface and the main reflection surface.
[0009] As a further technical solution of the present invention, a shell is welded to the bottom of the outer cover, and a semi-enclosed cavity is provided inside the shell. A strip light outlet is provided at the center of the inner part of the outer cover, and the strip light outlet is located at the top of the front end of the strip light guide.
[0010] As a further technical solution of the present invention, reserved holes are respectively provided on the rear sides of both sides of the bottom of the outer cover, insert tubes are respectively fixed on both sides and the front end of the center of the bottom of the outer cover, circular holes are respectively provided on both sides of the rear and the center of the front end of the interior of the light board, positioning holes are respectively provided on both sides of the front end of the interior of the light board, an insert block is installed on the left side of the bottom of the light board, positioning columns are respectively fixed on the front ends of both sides of the strip light guide, and a card block is fixed at the center of the rear of the top of the light board.

After the positioning column is embedded in the positioning hole, the two groups of LED light sources are respectively aligned with the V-shaped light incident surface, and the light incident wall and the light exit wall are in a vertical relationship. The first bevel corresponds to the third bevel, and the second bevel corresponds to the fourth bevel. The cross section of the light incident wall to the light exit wall gradually shrinks and decreases. After the LED light source emits light, it refracts outward when passing through the V-shaped light incident surface, which can reduce the brightness of the LED center, thereby supplementing the lack of brightness on the outside.
